IMPROVEMENT IN BOLTS FOR SAFES.

The Schedule referred co in these Letters Patent and making part of the same.

I, WILLIAM SHAnTs, lof Athens, iu the county of Greene and State of New York, have invented new and improved Mode of Fastening or Locking Bank- Safes, of which the following is a description and speci-V Iication.

Nature mu? Objects of thc Invention.

This invention consists of a combinationpof mechan-` ical devices so ai'ranged within the safe that they cannot be opeiated or even meddled with without alarmingr thcperson having it in charge.

The object is to dispense with all the ordinary modes lof fastening -with locks and keys, combination or other- Description of thc Accompanying Drawings.

Figure 1 is a perspective view of the locking-nicchanisiii in the interior of this safe.

Figure 2 is a perspective view of the exterior of the sate before being iuclosed in a brick or stone wall.

General Description.

The case or shell of my safe (sce fig. 2) is constructed in the nsiial rectangular form, in the most approved manner, and of the best materials, to render it both burglar-proof and fire-proof.

Instead of using a lock ofany of the ordinary constructions, which are inclosed in a separate box or case .and attached to the' inside of the door fora fastening, `with an aperture or key-hole leading into this case, I

employ a system of chainsor metal cords and pulleys which operate a bolt and bars within, none of which are coniined or inclosed in a separate case or boX,.nor canv they be operated or disturbed without the knowledge of the guard or officer having charge of the safe.

The opening-knob A (see fig. 2) may be on a gaspipe, its shaft or spindle passing through tbesaine, and used as a check or stop-valve. This use of it, however, would only be to avoid suspicion of its being employed for another purpose.

l The draw-wire i, extending across 1the under side of the top plate, is attached to the lock-bolt (l at one end, and is provided with a loop, k, at the opposite end, which 'may be connected with a bell or alarm in watchmans room ;A but merely withdrawing the bolt d does not alone enable the dooi' of the safe to be opened. It is necessary at the saine time to draw out the spindle of the knob A sniiicient for its inner. end, 7i., which is square, to fit into the inortise or socket of same form in the face of pulley B, and then, by revolving knob A in the right direction the door may be opened.

The operation of the mechanism for locking'and unlocking the door will be easily understood by referring to iig. 1 of the accon'ipanying drawings.

lVhen the bolt d is withdrawn the knob A, fig. 2, must also be drawn out, so that the opposite end, h, of the spindle, (which spindle is also the axis of pulley 13,) fits into the square inoi'tise or socket in the face of this pulley; then, by revolving the knob A from rear t-o front, (the door being in the front,) the cord or chain passing from the (nierating-pulley B down and around the lower series of pulleys, and which is attached to the lower end of the vertical connecting-bar C, will draw this bar downward toward the iioor or 'bottoni ot" the safe, and thus elevate the ends of the swing or lock-bars f f out of the brackets g g, which are attached to the inside of the door. The door is thus unlocked.

By revolving tbe knob A from front to rear operates the cord or chain which passes over and around thc upper series of pulleys, and, being attached to the upper end of connecting-bar C, draws it upward, throwing the opposite or outer ends of the 'locking-bars ff down and behind tho brackets g y. The door is thus locked.

rThe spiral spring m, enveloping bolt d, serves to restore it to its place when the wire't' is not being used for unlocking the door, and the slotted slide e is in position to allow the bolt to enter it, which locks the door.

It will be seen that the operating-spindle is of sufcient length to extend through a wall of any thickness, inclosing the safe.

C lai'ms.

That I claim is 1. Tlic combination of the vertical connecting-bar C with its lever-bars ff, spindle 7i, and system of cords Witnesses:
